Question

unit 3: statistics pre - exam question 25 of 29 (3 points) | question attempt: 1 of 1 here are the fuel efficiencies (in mpg) of 10 new cars. 28, 25, 30, 22, 16, 41, 35, 18, 52, 35 what is the percentage of these cars with a fuel efficiency less than 35 mpg?

Explanation:

Step1: Count cars below 35 mpg

The fuel - efficiencies less than 35 mpg are 28, 25, 30, 22, 16, 18. There are 6 such values.

Step2: Calculate percentage

The percentage formula is $\frac{\text{Number of cars with fuel - efficiency}<35}{\text{Total number of cars}}\times100\%$. Here, the total number of cars is 10. So the percentage is $\frac{6}{10}\times100\% = 60\%$.

Answer:

60%
